These cells activate many immune cells (including B and T). Then can also deactivate immune cells.

Thelper / CD4

These cells rid the body of cells that have been infected by viruses as well as cells that have been transformed by cancer. They are also responsible for the rejection of tissue and organ grafts.

Cytotoxic T / CD8

This cells functions by secreting soluble substances known as antibodies. Each one is programmed to make one specific antibody. They give rise to plasma cells which are factories for making the specific anitbody.

B Cells

These cells are diverse and potent chemical messengers secreted by cells of the immune system -- and the chief tool of T cells.
These cells recruit many other cells and substances to the field of action.
These cells can encourage cell growth, promote cell activation, direct cellular traffic, and destroy target cells (i.e. cancer cells).
They serve as a messenger between white cells.

Action is immediate.
Response is non-specific.
Response is not enhanced on repeated exposure to pathogen.
